The beginning of the story is just a long description about Kino’s village. It is an Indian village in Mexico.
Kino wakes up and he and Juana eat breakfast.
Kino sings some traditional song about family and it makes him happy.
Then a scorpion crawls into Coyotito’s crib and stings him.
Kino gets mad and kills the scorpion. The baby is hurt and then the whole village comes to see what’s going on
Juana tells Kino to get the doctor. It’s hard for her to call the doctor because the Indians are poor and the doctor is a rich jerk and he doesn’t care about Indians because they are poor
Juana realizes the doctor isn’t coming to the village so she takes Coyotito to his house for treatment.
So all of the villagers, Juana, and Kino go to the doctor’s house for help. They get there and the doctor won’t let them in.
The doctor acts like a real jerk and insults the Indian people. Kino gets mad and punches the gate outside the doc’s house.
The rest of this chapter just describes the difference between the doctor and the villagers -- he’s a rich, snazzy dude and the villagers are poor.
